A highly thermally stable twistarene, namely 11,16‐di‐tert‐butyl‐9,18‐diphenylbenzo[kl]benzo[8,9]triphenyleno[2,3‐b]xanthene (BTX) , has been synthesized via a simple reaction, and its structure was unambiguously determined by single crystal X‐ray analysis with a twisted angle of 37.9° between plane C1‐C2‐C4 and plane C16‐C17‐C24. More interestingly, molecule BTX could self‐assembly into nanowires and nanospheres via simple reprecipitation, which were characterized by scanning electron microscope (SEM), UV‐vis absorption and emission spectra. The fabricated electroluminescent devices based on BTX as active ingredient presented a maximum brightness of 4355 cd m −2 (bias voltage at 9.0 V) with CIE coordinate of (0.14, 0.53).
